Leaves of pseudognaphalium thermale are long, up to 3 inches, and narrow, less than a quarter of an inch across. They have a prominent midvein, and a white tomentose hair covering, thick enough to mostly obscure the stalked glands on the surface. Both sides of the leaves are similar in appearance. Upper stem leaves are reduced in size. Stems are also tomentose, though not glandular.
Flowerheads are arranged in moderately dense clusters; they have a bell-shaped involucre ringed by three or four series of ovate white phyllaries, hairless and somewhat shiny. There are four to seven disc florets, and between 35 and 55 ray florets.
